There are probably better ways to set up the data structure, such as:
}
Type
tCardVal = (Two, Three, Four, Five, Six, Seven,
Eight, Nine, Ten, Jack, Queen, King, Ace);
tCardSuit = (Spades, Diamonds, Hearts, Clubs);
tCard = Record
val : tCardVal;
suit : tCardSuit;
end;
Const
valStrings : Array [tCardVal] of String[5] =
('Two', 'Three', 'Four', 'Five', 'Six', 'Seven',
'Eight', 'Nine', 'Ten', 'Jack', 'Queen', 'King', 'Ace');
suitStrings : Array [tCardSuit] of String[8] =
('Spades', 'Diamonds', 'Hearts', 'Clubs');
Var
deck : Array [0..51] of tCard;
{ after initializing the deck, you could shuffle With a Procedure like this: }
for i := 300 + random(50) downto 0 do
begin
posn := random(51);
tempCard := deck[posn];
deck[posn] := deck[posn + 1];
deck[posn + 1] := tempCard;
end;
{
This might be better if it swapped two randomly-picked cards, would shuffle
better... }
